Ultrasonic velocities and densities of the binary liquid mixtures of ethyl benzoate with 2-methoxyethanol, 2- ethoxyethanol and 2-butoxyethanol have been measured over the entire composition range of mole fractions at a temperature range from 303.15 to 318.15 K with an interval of 5 K. The theoretical values of ultrasonic velocity were evaluated by using Nomoto (NOM), Impedance (IMP), Van Deal and Vangeel (VDV), Junjie’s (JUN), Rao’s specific velocity (RAO) models. The results were discussed in terms of non-ideality in the mixtures, molecular interaction parameter, relative deviation σ and Chi-square (χ 2) test for the goodness of the fit is applied to understand the applicability of these theories to the present systems.
